Finally able to get to some gate jobs I started last week. 4 total double drives for the local school district and a church. 1.625 SCH40, painted and galvanized. 3 were already being covered so didn't snap any pics. Fun stuff...
So glad I made the jump back into welding full time.

One of the delivery drivers at my day job broke the handle on his 2 wheeler. Got it cleaned up and with some creative clamping, got it out back together. They break these things all the time in various places.

A new gate that just got finished. We havent done this design before and I thought it looked cool.
Also a foot plate weld from earlier in the week. Both parts are anodized aluminum and welded in the position shown.
Changed out a condenser yesterday.
Here's the new one going in:

Here's the finished ammonia pipework:

4" condenser coil connections were carbon steel to sched 10 grade 316. Used 309 wire.
2-1/2" sched40 liquid dropper required a 45mm (about 1-3/4")pup to line up to the coil stub.
Weather was nice and no wind. All went good for a change. See, I get good jobs too but mostly they are just pipework and I usually can't take pics. The "star" jobs I get mostly end up in the shop where I can take pics, and are have some extra interest because they are unusual and have some problem solving requirement.
A condenser is part of a refrigeration system. High pressure compressor discharge hot gas enters into a serpentine pipe coil inside the case where it is blasted with air and water causing the high pressure hot gas to condense into high pressure liquid.
This particular one is an evaporative condenser having the water spray addition to the fan forced air. the spray water evaporates partially in the presence of the hot coils and air blast making it more efficient than pure air only cooling. Your domestic fridge equivalent is the black coil at the back of (or underneath for modern) the fridge. Your car air con has a condenser coil bolted in front of the radiator. Does the same thing only this one is bigger and is obviously part of an industrial system and using ammonia as the refrigerant hence the need for steel pipes.
As far as industrial evaporative condensers go, this is a small one. The biggest one I've installed weighed 30T, had 50hp fans and was mounted on a 6m high stand. My American brothers (like Josh) probably installed bigger ones.
Nice one Cold! Working at a small plant now that’s adding an ice builder, and another Vilters 450, along with some cooler space. Pretty sure there gonna need another condenser soon too. Just for capacity but also for redundancy.

Little bit of Amonia pipe. Had to pressure test the underground pipe at 375psi. But needed to add a block and bleed valve set to isolate a pump that could only handle 250psi. Replaced a threaded Union with some flanges while we had it down.

Nice one Josh. Is that 2"?
What brand of valve is that?
Is it a fertilizer job and is red the normal color code for ammonia over there or is it just what they used on that plant?
It’s 3inch. The valves are from R/S. Think it stands for refrigeration specialty. Orange is how this place labels there liquid lines. It will be for a farm service place but at this point in the system it’s still at 80% pure or above.
Should’ve known from the color they were rs. Just never seen one before, the rs hand valves never made it down under, only the control valves. Don’t like em though. Hansen’s got it all over them.
Had to cut and blank a 6" pipe and a 2" pipe for equipment removal.

Two ladders and a squeezed catwalk to get my gear up onto the roof. Yay.
Didn't get a full set of pics because half way through a cold front arrived and I rushed to finish before the wind picked up. It did, I had to do the 2" cap with a No.4 cup and the argon turned up full blast to keep the weld pool shielded. All good.
had to repair this.
i bought a cheap freight damaged frame from a welding store and it looks like someone replaced a part.
looks like flux core, no slag removed just painted over. didn't see any cleaned spot for earth clamp.
it also didn't fit well.

cut apart, tig back together. used old 2.4mm tig rod as packers to fill in a big gap.
quick grind and splash of paint.
A little Saturday afternoon project today, a carpenter buddy of mine wanted some carts made for his cabinetry shop. I thought this was a pretty simple design, it’s 30’ of 2x2 by 3/16 angle, 6’ and 5x1/4 flat bar for the casters to bolt to. Turned out all right I’d say. I told him I’d make one now in exchange for free range of his shop next Saturday and all the lumber I need for a new table and shelving in my storage room at work. And I’d make more in winter as I find time. He agreed
He’ll just lay on a 3/4 sheet of plywood on top and cover it with carpet to avoid scratching his work pieces. Same with underneath. He’s happy, I’m happy

Looks good, best of all it's a win-win for everyone

I'll bet it was nice to weld something that didn't have to do with potatoes!
